IMPROVED RAILWAY-CAR AXLE.

To all whom it may concern Be it known that I, E. T. LIGON, of Demopolis, in the county of Marengo, and State of Alabama, have invented a new and improved Gar-Axle; and I do hereby declare that the following is a f'ull,clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawings, forming part 'of this specification, in which-- Figure I is a side view of my'improved car-axle, part being broken away to show the construction.

Figure 2 is a cross-section of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the construction of car-axles, so as to malke them stronger, less liable to break, and less liable to fail or part suddenly whtim injured, or when there may he a flaw in the metal; an

' It consists in the construction of the axle, as hereinafter more fully described. 7

Ais an iron or steel tube,'made of the desired form and size, and which is coated upon the inside with copper, tin, zinc, or other suitable and comparatively soft metal.

B is a wire cable, made of steel, iron, or copper wire.

The cable B is also coated with copper, tin, zinc, or

other suitable and soft metal, and is made of a suitable-size to fit into the tube A.

The whole is then brazed, or united by galvanic process into a solid mass. By this construction, the axle is made stronger and less liable to break, the softer,v metal 0 interposed between the outertube or shell A and the inner cable B,

acting as a cushion to interrupt or check the vibrations,

and consequently preventing the crystallization of the steel tube or shell, an inner-wire cable, and an inter posed filling of softer metal, substantially in the man- 'ner herein shown and described, and for the purpose set forth.
